Government affair video data processing method and system and computer readable storage medium

The invention discloses a government affair video data processing method and system and a computer readable storage medium, and belongs to the technical field of data processing. The processing method comprises the following steps: segmenting a field video stream into a plurality of sub-videos based on a time sequence, and marking a frame identification code on the field video stream; and modifying the live video stream according to the inter-frame features to generate a first video stream, extracting a plurality of video clips from the first video stream, and generating a second video stream. And if the content frame of the second video stream is abnormal, establishing a priority list according to the frame identification code, and downloading the sub-video from the storage node based on the priority list. According to the invention, the on-site video stream is segmented into a plurality of sub-videos, distributed storage of the video stream is realized, and local storage requirements are reduced.
